由于根管系统的复杂性,传统的根管预备器械与冲洗剂难以达到完全清理根管的目的。Er∶YAG激光联合根管冲洗剂使用,既可以采取更保守的根管预备,又能增强去除玷污层、开放牙本质小管和杀菌的能力,有利于根管封闭剂和根管内黏结剂的渗透而减少微渗漏;且在一定的激光参数范围内,其不会引起冲洗剂的根尖渗出;产热作用也极小,不会引起根尖周组织损伤。因此,Er∶YAG激光的应用能使根管预备过程变得简单、高效、安全。本文综述了Er∶YAG激光在根管治疗中的应用研究进展。
Due to the complexity of the root canal system, the traditional root canal preparation equipment and irrigation agents are difficult to achieve the purpose of completely cleaning the root canal. The use of Er:YAG laser combined with root canal irrigator not only allows for more conservative root canal preparation but also enhances the ability to remove smear and open dentinal tubules and sterilize them and is beneficial for root canal sealers and root canal adhesives Infiltration and reduce microleakage; and within a certain range of laser parameters, it does not cause the root tip of the irrigation agent exudation; thermogenesis effect is minimal, will not cause periapical tissue damage. Therefore, the application of Er: YAG laser can make root canal preparation process simple, efficient and safe. This review summarizes the application of Er:YAG laser in root canal therapy.
